Time in Milliseconds

[bronxbomber92]

What are you using currently to get the time?

GetTime() has nanosecond resolution, Timer::GetFPGATimestamp() has microsecond resolution, and the Timer class has microsecond resolution.

Oh we were using the time class (time.h). We did not notice the timer class.

By the way, changing the resolution of the clock using low level VxWorks routines may wreak havoc on the timing of the rest of the system. Obviously you can do so, but do it carefully and test well.

use Wait(double seconds);
or a Timer

BTW, in case you haven't found an optimal solution, I just implemented a GetMsecTime() macro today. The timer object seems a bit heavy to me. This is simple yet functional.

#define GetMsecTime()           (GetFPGATime()/1000)

If you want something simple and fast, use the standard C library's ctime (also known as time.h).

the function clock() returns the amount of ticks that have passed since your program started running as a clock_t value. The amount of ticks per second is defined in the macro CLOCKS_PER_SEC. Using this and some simple dimensional analysis, you can easily get how many miliseconds have passed between two clock() calls.
